The present invention relates to valves, and, more particularly, to valves ttor proportioning the iiow of gaseous medium under pressure through two passages.

Accordingly, an object oi the present invention is to provide an improved valve of the foregoing type.

Another object is to provide such a valve which can be utilized to cause the gaseous medium to produce desired operations.

A further object is to provide such a valve which is simple, practical and economical in construction, and is accurate and reliable in operation.

Other and further obiects or the invention will be obvious upon an understanding ot the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

In accordance with the present invention, the foregoing objects are generally accomplished by providing a valve which comprises a body formed with chamber means having inlet means tor connection to a supply of gas under pressure and having two independent outlets for directing the gas to its point oi use, a fixed element in the chamber means having two openings disposed in a common plane at one side of the element and having a partition between the openings for isolating the openings from each other, both of the openings being in i'low communication with the inlet means upstream ot the outlets and each of the openings being in ilow communication with only one of the outlets, a control member mounted tor sliding movement across the openings at the upstream side of the openings and constructed and arranged tor opening one of the openings while closing the other of the openings and vice versa, and means for effecting movement of the control member.

A preferred embodiment of the invention has been chosen for purposes of illustration and description, and is shown in the accompanying drawing, forming a part of the speciiication, wherein:

FIG. l is a longitudinal sectional view of a valve in accordance with the present invention.

FIG. 2 is a sectional view taken along the line 2-2 on FIG. 1.

Referring now to FIGS. l and 2 of the drawing in detail, a valve llt) is shown which comprises a valve body llll provided with a chamber l2 formed with an inlet 14 for connenction to a source ot gaseous medium under pressure (not shown) and a pair of outlets and i6 for connection to the point of use of the gaseous medium; a block 17 anchored in the chamber l2 having a post i8 thereon and being formed with a pair of outlets 19 and 2@ respectively in flow communication with the outlets 15 and 16 and with pairs of openings or ports 2l and 22 in opposite flat sides 24 of the block, the openings 2l and 22 being isolated by a partition 25 and being in flow communication with the chamber l2; a control member 26; and motor means 27 for operating the control member.

The control member 26 includes a pair of dat plates 23 rigidly mounted by a cross-piece 29 on a lever 3l? which is pivotally mounted at Fill on the post iti to slide the plates Ztl across the flat sides 24 at the upstream side of 3,234,957 Patented. Feb. l5, 'i966 the ports or openings Zi and 2.2 in the block l and to thereby control the extent of uncovering of the ports; and a connecting rod 32 operated by the motor means 27 to oscillate the plates 2S across the ports 2i and 22. The lower ends ot the plates 28 are secured against spreading apart by a bolt 34 so that gaseous pressure cannot ilex the plates and cause unclosing of the ports when the ports should be nearly or fully closed,

The valve l@ is adapted for alternately creating thrusts in opposite directions by discharging gaseous medium under pressure through typical space nozzles N of a missile which nozzles are connected to the outlets l5 and l5 ot the valve body il. The valve is also adapted for controlling the operation ot gaseous pressure medium powered apparatus (not shown) by connecting the outlets i5 and i6 to inlets of such apparatus.

ln operation, gaseous medium under pressure enters the chamber l?. by way of the inlet i4 and exits by way of the ports or openings Zi and 22 and the outlets 19 and 29 in dow communication therewith while the position of the control member 25 determines the flow rate ot the gaseous medium through the respective pairs of ports Zit and 22.

From the foregoing description, it will be seen that the present invention provides an improved control valve or numerous purposes where the ilow of gaseous medium under pressure is to be proportioned to provide a thrust adapted for steering missiles and the like or to effect operation of mechanisms.

As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacricing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.

We claim:

ll. A valve comprising a body provided with chamber means having inlet means for connection to a supply of gas under pressure and having two independent outlets for directing the gas to its point of use, a iXed element in said chamber means having a pair of aligned openings disposed in a common plane at opposite sides of said element and having a partition between said openings for isolating said openings from each other, both of said openings at each side being in flow communication with said inlet means upstream of said outlets and each of said openings at each side being in ilow communication with only one of said outlets, a control member having a pair of connected plate portions mounted for sliding movement across said openings at the upstream side of said openings at each side and each plate portion being constructed and arranged for opening one of said openings while closing the other of said openings and vice versa at one side of said element, and means for edecting movement of said control member.

2. A valve according to claim 1, wherein said control member is pivotally mounted to oscillate said plate portions across said openings.

3. A valve according to claim 2, wherein said plate portions are rigidly connected at both ends thereof to prevent distortion thereof by the gas under pressure.
